halo not hello ok...
Two phenomena involving the sun had Klang Valley and Johor folk snapping away to capture the moment.
The strange sight of a halo circling the sun became a talking point here as many were seen using their handphones to capture the spectacle at about 12.30pm Tuesday.
The National Space Agency (Angkasa), however, gave assurance that the phenomenon was not something to be alarmed about.
The “rainbow-around-the-sun” effect oc***curs naturally when light interacts with ice crystals in cirrus clouds.
The crystals act like prisms, refracting and reflecting sunlight to produce a rainbow-coloured effect around the sun.
However, the agency advised people not to stare directly into the sun to protect their eyesight.
